Tetraselenium tetranitride is the inorganic compound with the formula Se
4N
4. Like the analogous tetrasulfur tetranitride S
4N
4, Se
4N
4 is an orange solid. It is however less soluble and more shock-sensitive than S
4N
4.^[2]

As determined by X-ray crystallography, Se
4N
4 adopts a cage structure similar to that of S
4N
4. The Se–Se and Se–N distances are 2.740 and 1.800 Å, respectively. The N–Se–N angles are 90°.^[1]^[3]

Among its many reactions,^[4]^[5] Se
4N
4 reacts with aluminium chloride to form adducts of Se
2N
